LED Faucets are every popular these days. They
Featrues of LED Glass Waterfall Basin Bathroom Sink Tap Faucet:
The amazing aspect of the LED faucet is temperature sensor and three groups of small LED lights around the spout. When the water flows through the glass tray, the temperature sensor could detect the water temperature and reflect the result to the circuit, thus the lights which could illustrate the different temperature range could be controlled easily. Therefore, you could only 'see' the water temperature without feeling it; this design protects your family not to be scald accidently, especially for the kids and senior citizens.
Please kindly take notes that the LED light only works while faucet is open, and could only afford 2kg of water pressure.
Instructions on Installing A LED Faucet:
 Remove your existing shower head with a wrench. Set the wrench in place and turn the nut to the left to loosen it. Have a hand ready to catch the shower head when it falls so that the metal doesn't crack your shower floor.
 Clean the threads of the base of the shower faucet with steel wool. Be sure to remove any debris that had collected around the threads. It's a good idea to put down some newspaper or paper towels in the tub so that you can remove the debris instead of washing it down the drain.
 Wrap the faucet threads with thread tape. This tape comes with almost all new shower faucets and heads and provides traction for the new hardware.
 Place a rubber 'O'-ring inside the new shower head at any place that there is a water connection. This prevents a leaky faucet and improves water pressure.
 Tighten the hardware with a wrench. Turn the wrench to the right to tighten. Test the Temperature Controlled LED Faucet to make sure there are no leaks and that everything is working properly.
Now you have a huge improvement in your bathroom for a minimal amount of cost and effort.
